notwithstanding anything to the contrary in any Transaction Document, Holder shall not be obligated to purchase Notes at any Mandatory Tranche Closing or any Optional Tranche Closing or to otherwise extend any credit to the Company pursuant to any of the Transaction Documents; provided, any representations and warranties of the Company pursuant to the SPA that are deemed given as of a Mandatory Tranche Closing Date or Optional Tranche Closing Date shall not be so given if Purchaser declines to purchase Notes at such Mandatory Tranche Closing or Optional Tranche Closing; and

Holder has fully and timely performed all of its obligations and duties in compliance with the Transaction Documents and applicable law, and has acted reasonably, in good faith and appropriately under the circumstances.

that Section 4(a)(v) of each Outstanding Note shall be amended and restated in its entirety and replaced with the following:

that Article I of the Outstanding Notes is hereby amended by deleting the definitions of “Mandatory Conversion Date”, “Mandatory Conversion Event”, Mandatory Conversion Notice” and “Mandatory Conversion Notice Date” and Section 4(a)(ii) and Section 4(a)(iv) of the Outstanding Notes and Section 4.18 of the SPA are each hereby amended and restated and replaced with the following:

[Reserved].

Forbearance. Subject to the satisfaction of the conditions precedent set forth in Section 9 below, Holder agrees, (i) with respect to the Subject Defaults (but only the Subject Defaults), that it will refrain and forebear from exercising or pursuing any rights or remedies (other than as set forth in Sections 2(e) and 3 above) under the Outstanding Notes or any other Transaction Document until (but only until) the Forbearance Termination Date (defined below), and (ii) with respect to any interest that has accrued and is owing as of the date hereof and any interest that shall accrue and be payable from the date hereof until the Forbearance Termination Date, Holder agrees that such interest shall be deferred and not payable until the first Business Day following the Forbearance Termination Date. The Company agrees that until such time that any such accrued and unpaid interest is paid in cash, the Holder may convert such accrued and unpaid interest into shares of Common Stock in accordance with Article IV of the Outstanding Notes. Any term or provision hereof to the contrary notwithstanding, Holder is not waiving any of its rights or remedies under the Outstanding Notes or any other Transaction Document, but instead is simply agreeing not to take remedial action (other than as set forth in Sections 2(e) and 3 above) with respect to the Subject Defaults until the Forbearance Termination Date.
